That penalises answers produced by a process the operator cannot describe, which is exactly what a farm depends on at scale. Every accepted answer must be reproducible from its published inputs within 7 epochs, and one that cannot be regenerated is retired with its standing forfeit. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":7,"sig":"3F1FM61UijxD22fFtESFhUCTga7DPs1bjZLpBQjbPTvDrJwEcigbZgosrMRNaqzAhnAhHeWGLz7WoGrnqN5htxmP"},"checkpointed":{"height":188268,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:54:16.205Z","checkpoint_height":188268,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
